This tile is one in a series which probably once formed a glittering inscriptional frieze encircling the walls of a 14th-century tomb pavilion located in Natanz, Iran. The cobalt-blue inscription is set against a field of scrolling vines, wherein tiny birds perch amongst leafy foliage, some alighting upon the letters themselves. The frieze likely sat close to eye level, permitting the intricacies of the tile's drawing to be admired, while crowning a dado of equally opulent star- and cross-shaped tiles.
